Question

A boy walked to his friend house 12 miles away. If he averaged 2.5 miles per hour, how many hours did it take to reach the house ?

Answer 1

Hello there,

Friends house: 12 miles
Average: 2.5 mph

Write a proportion...

12/x = 2.5/1

Cross multiply and divide...

12 * 1 = 12

12/2.5 = 4.8 hours

Convert that into time...

4.8 hours or 5 h 20 m


Hope I Helped!!

Answer 2

4.8 hours

Explanation:

The speed of the boy is 2.5 miles per hour. Speed is defined as distance over time:

`V=d/t`

We have the speed and the distance and therefore we can work out the time in hours:

`2.5=12/t`

`t=12/2.5=4.8`

The boy took 4.8 hours to reach the house
